Low price non pressure solar water heater with assistant tank

   Working principle of Non-pressurized Vacuum Tube Solar System 
1. Solar vacuum tube was evacuated into the tank, the coating inside of tube can 
absorb heat energy from sunshine.  
2. The cold water in water tank flows into the tube and become hot because of different 
density between cold and hot, there will  be a natural circulation in the tube. Hot water 
will float back to tank. 
3. The polyurethane heat insulation layer can keep the water warm about 3 days without 
any sunshine. Consumer can enjoy comfortable bathe anytime.
